The future of atmospheric measurement for wind energy.

We're creating the future of weather forecasting, the world's first weather forecasting using VTOL drones.

The weather has been measured the same way for a hundred years.

The data gap isn't a model problem. It's a measurement problem. You can't correct what you can't see. That changes now.

Models have improved throughout the century, but the measurement has stayed the same.

We are changing that.

Introducing weather forecasting using VTOL drones.

Our technology on the drone measures the atmospheric data needed for the future of weather forecasting.

We fly through the atmosphere and measure it directly.

A curtain of measurements whenever needed

One pipeline, one owner: sensor → model → forecast.

From the air above the site to a corrected forecast.

  1. 01Measure

    VTOL drones profile the vertical wind layer that regional models only approximate: near site, at hub height.

  2. 02Model

    Windwall, a physics-informed neural operator, detects when HARMONIE or ICON is failing at a site and anchors the forecast to real measurements.

  3. 03Deliver

    A corrected intra-day forecast, delivered via API, priced as a share of measured savings against the free IFS baseline.

Mapping the whole world.

To make the weather measurable everywhere it matters, starting with the turbines that power the world.

From air to action.

Every place deserves weather intelligence as precise as its own air.
